Barcode 39 does not render correct when printing

[ErikG]

Hello!
We have used pxcview.dll for years (more than 5) to print pdf on user computers. We have only had a few issues where printing have gone wrong, so I am evaluating the latest build (from PDFXChange PRO bulid 5.5.315.0). This solves the issues, but another comes up instead: barcode printing is not rendering correct any more (on OneNote or PDF-XChange printer driver). It works om my nearest printer, but I want to make sure it will work on every printer. I enclose a few samples.

Hello ErikG,

Can you please send us all the printing parameters that you are using?

Regards,
Stefan

Hello ErikG,

Thanks for the code.
Can you please try to remove the pxvrpf_UseVectorRenderer flag? Your output is image based anyway - so this is not needed, and might allow you to generate the correct PDF files.

Regards,
Stefan

Hello Stefan!
I am sorry, but removing the pxvrpf_UseVectorRenderer did not work. Only change was that colors were replaced by grayscale. I have a small testbench which just pick up the pdf and sends it to my print routine, so I am certain that nothing else is interfering.

Can you please add flag pxvrpf_EmbeddedFontAsCurves to the pParams.Flags ?

[ErikG]

Hello Ivan and thanks for your prompt reply.

Only adding pxvrpf_EmbeddedFontAsCurves to pParams.Flags did not do the trick. The color came back, but the document went black See test 1. But when I combined that flag with pxvrpf_UseVectorRenderer as in

pParams.Flags = pxvrpf_UseVectorRenderer | pxvrpf_EmbeddedFontAsCurves;

I got what I wanted! . See test 2.

Hi Erik,

Glad to hear you got the desired result!

Cheers,
Stefan
